The four year investigation has come to an end with the following results:
- 80% reduction of footprint for the technology implementation, i.e compact treatment systems compared to conventional treatments, such as a conventional activated sludge (CAS).
- AGS CAPEX resulted 20-50% lower than CAS for the treatment of high strength wastewater.
- Total costs savings calculated for AGS and MBBR prototypes ranged between 49-51%, compared to the current DAF technology, including the additional investment required to renovate the plant. If only OPEX is considered, savings reach 72%.
- Important reduction in estimated environmental welfare damage in both biofilm-based technologies for the case of eutrophication.
- AGS decrease up to 74% the expected value of damage to river ecosystem and nearly 90% in the case of marine ecosystems
- MBBR decrease 65% expected value of damage to river ecosystem and 70% in the case of marine ecosystems
- The results of DOQ and Nitrogen removal for the different technologies have reached:
- MBBR system. Removal efficiency higher than 70% (COD and N) in low-strength wastewater treatment.
- AGS system. On the one hand, COD removal efficiency of 70-80% and up to 90% of total nitrogen in low-strength wastewater treatment. On the other hand, COD removal efficiency of 80-90% and between 30-40% of total nitrogen removal in high-strength wastewater treatment.
The monitoring of the benthonic ecosystem demonstrated the need to implement sustainable and effective technologies for the treatment of complex fish canning wastewaters.
Biofilm-based technologies are suitable and efficient alternative systems for the treatment of biodegradable industrial wastewaters, including fish canning wastewater, dairy industry and other effluents from the food and beverage sector.
